Yoshua Bengio, considered by many to be one of the godfathers of AI, has long been at the forefront of machine-learning research . However, his opinions on the technology have shifted in recent years — he joins us to talk about ways to address the risks posed by AI, and his efforts to develop an AI with safety built in from the start. Nature: ‘It keeps me awake at night’: machine-learning pioneer on AI’s threat to humanity Hosted on Acast. See acast.com/privacy for more information....
00:45 A coronal mass ejection from a distant star Researchers have detected what they say is the strongest evidence yet of a coronal mass ejection (CME) coming from a star other than our Sun. CMEs are massive bursts of fast-moving plasma that can be detected thanks to the characteristic radio signal they produce. However, despite decades of searching, these signals have only been identified from the Sun. Now a team has identified a similar signal coming from a distant star in the Milky Way. They...
00:45 The debate around Nanotyrannus A hotly debated species of dinosaur, assumed by many to be a juvenile T. rex, is actually a separate species, according to new research. Nanotyrannus was a dinosaur anatomically similar to T. rex, but about a tenth of the size, leading many to argue it was a young version of the iconic species. However, examination of the limb bones of a well-preserved Nanotyrannus fossil suggests it was close to finishing its growth and so would never become as large as a T....
This episode explores how bowhead whales live over 200 years, highlighting the discovery of a cold-induced RNA-binding protein (CIRBP) that enhances DNA repair, offering potential insights for human anti-aging and cancer prevention. Additionally, researchers detail a breakthrough in creating a broad-spectrum, nanobody-based antivenom, a crucial step towards more effective and accessible treatment for millions affected by snakebites worldwide.
Advice on how to get good sleep is everywhere, with the market for sleep aids worth more than US$100 billion annually. However, scientists warn that online hacks and pricey tools aren’t always effective, and suggest that lessons learnt about the workings of a network of biological clocks found in the human body could ultimately lead to improved sleep. This is an audio version of our Feature: How to get the best night’s sleep: what the science says Hosted on Acast. See acast.com/privacy for more ...
00:48 How hunger, hormones and aggression interact in mouse brains Researchers have uncovered the neural mechanisms that underlie an aggressive behaviour in mice prompted by hunger and hormonal state. Virgin female mice can become aggressive towards mouse pups when they are food deprived, but it seems that the relevant amounts of pregnancy hormones, oestrogen and progesterone, also played a role. By investigating the neurons involved, neuroscientists showed how hunger and hormones are integrated...
00:46 A multi-variant avian flu vaccine that could enhance pandemic preparedness A vaccine capable of protecting against multiple strains of avian influenza virus might be a step closer, according to new research. The H5 subtype of avian influenza viruses has spilled over into mammals and is particularly concerning to researchers because of the risk that one of its variants may evolve to cause a pandemic. But because there are multiple variants of these viruses, it has been hard to pre-prepare v...
00:48 The stereotypes hidden in Internet images Stereotyped assumptions about women’s ages and their perceived job suitability are enhanced by Internet imagery, according to new research. A study of hundreds of thousands of online images shows that women appear younger than men. This stereotype extends to the jobs that people perceive women do, with men being associated with roles such as CEO or head of research, while women were linked to occupations like cook or nurse. The research shows that ...
00:50 How ancient viruses drive modern human development Research suggests that ancient viral-DNA embedded in the human genome is playing a key role in early embryo development. Around 8% of our genome consists of endogenous retrovirus DNA — the remnants of ancient infections, but knowledge of their activity is limited. Now, a team show that these sequences are required for the correct development of lab-derived embryo analogues, and for the switching on of human-specific genes. Research Article...
In April, Robert F. Kennedy Jr held a press conference about rising diagnoses of autism, and said he would soon be announcing a study to find the responsible agent. Although Kennedy said that environmental factors are the main cause of autism, research has shown that genetics plays a bigger part. Also, the rise in prevalence, many researchers say, is predominantly caused by an increase in diagnoses rather than a true rise in the underlying symptoms and traits. Although the US National Institutes...
00:48 New insights into tick-borne encephalitis Researchers have identified a key protein that helps tick-borne encephalitis virus enter the brain. In rare cases an infection can lead to serious neurological symptoms, but little was known about how the virus interacts with human cells. Now, a team show that a protein found on the outside of cells plays an important role in infection. In mouse experiments, they show that blocking the ability of the virus to bind to this protein protected the mice...
Science journalist Lizzie Wade’s first book, Apocalypse: A Transformative Exploration of Humanity's Resilience Through Cataclysmic Events explores some of the cataclysmic events that humans have faced through history. Lizzie joined us to discuss what modern archaeology has revealed about these events, and the role these they’ve have played in shaping societies around the world. Apocalypse: A Transformative Exploration of Humanity's Resilience Through Cataclysmic Events Lizzie Wade Harper (2025) ...
00:50 The AI tool that predicts disease risk Researchers have developed an AI tool that can calculate a person’s risk of developing over 1,000 different diseases, sometimes years in advance. The system, called Delphi-2M, was trained to identify patterns of disease progression using 400,000 people's health records from data repository the UK Biobank. This training allowed it to predict someone’s future disease risks, based on their current medical record. While AI health prediction systems do exi...
In 2015, the Laser Interferometer Gravitational Wave Observatory (LIGO) facilities in the US directly detected ripples in space-time, known as gravitational waves. These waves were produced by the final spiral of two orbiting black holes that smashed into each other, sending ripples across the Universe. In this podcast, Benjamin Thompson speaks to Cole Miller from the University of Maryland about the quest to detect gravitational waves, which were first hypothesised by Albert Einstein back in 19...
00:45 Attributing extreme heat events to major energy producers Major energy producers increased the likelihood and intensity of heatwaves, according to research published in Nature . Using data from an international disaster database, a team developed a methodology to investigate how much anthropogenic climate change had influenced heatwaves. They conclude that many of these events would have been “virtually impossible” without climate change, and that nearly a quarter of the heatwaves recorded...
In 2016, Brian Wansink wrote a blog post that prompted scientific sleuths to investigate his work. They found evidence of data manipulation, and, after several news articles and two investigations by his institution, he would found to have committed misconduct, as defined by Cornell University. His work had been used to inform US policy around food, much of which has now been thrown into question. Cases like this are rare, but science is not immune to misconduct. The rise in 'paper mills' — orga...
Raising mosquitoes to tackle disease might sound like an odd concept, but that’s what a facility in Brazil is aiming to do. Millions of mosquitoes are produced there every week, but these insects carry harmless Wolbachia bacteria that curbs their ability to spread deadly human viruses. Nature reporter Mariana Lenharo visited the facility and told us all about her experience in this Podcast Extra. News: This is the world’s largest ‘mosquito factory’: its goal is to stop dengue Video: Inside a mos...
00:45 The ant queen that can produce two different species Researchers have made an unusual observation that appears at odds with biology: an ant, known as the Iberian Harvester Ant can produce offspring of two completely different species. Many ants need to mate with other species to produce workers that are a genetic mix of the two, known as hybrids. But in Sicily, a team found hybrid worker ants but no trace of the father. They suggest that the one species present, Messor ibericus, is able to...
This episode delves into the evolving science of detecting consciousness, beginning with groundbreaking neuroimaging techniques used in unresponsive human patients and the "onion layers" of testing, from observing external behaviors to intrinsic brain properties. It then expands to challenges and methods for identifying consciousness in non-human animals, influencing welfare policies, and debates the potential emergence and testing of consciousness in artificial intelligence systems. The discussion concludes with proposals for a universal strategy to detect consciousness across diverse systems.
00:48 How the 18th-Century 'Great Fear’ spread across rural France In the late 1700s, rural France was beset with rapidly spreading rumours of aristocratic plots to suppress revolutionary ideas. But how, and why, these rumours were able to spread so quickly has puzzled historians. Now, using modern epidemiological modelling, a team suggests that a combination of high wheat prices, income and literacy level drove this period of French history known as the Great Fear. Research Article: Zapperi et ...
00:46 Electrochemical fusion Researchers have used electrochemistry to increase the rates of nuclear fusion reactions in a desktop reactor. Fusion energy promises abundant clean energy, but fusion events are rare, hindering progress. Now, inspired by the controversial claim of cold fusion, researchers used electrochemistry to get palladium to absorb more deuterium ions, that are used in fusion. When a beam of deuterium was fired at the deuterium-filled palladium, they saw a 15% increase in fusio...
In this Podcast Extra, we discuss a report released by the US Department of Energy, which concluded that global warming is “less damaging economically than commonly believed”. However, many researchers say that the report misrepresents decades of climate science. We discuss how scientists are trying to coordinate a unified response amidst concerns that this report will be used in attempts to repeal a 2009 government ruling that greenhouse gases endanger public welfare. News: Outrage over Trump t...
00:46 Tiny solar flyer Researchers have used a phenomenon known as thermal transpiration to create a solar-powered flying device that can stay aloft without any moving parts. The diminutive device, just one centimetre across, consists of two thin, perforated membranes that allow air to flow through the device, generating lift. Although only a proof-of-concept, the team hope that a scaled-up version of the device could be used to measure conditions in the mesosphere, a particularly hard-to-study ...
00:45 Researchers develop a new glue and test it on a rubber duck Aided by machine learning, researchers have developed a super-sticky compound that works as an underwater adhesive. Inspired by animals like barnacles, the team developed a new kind of a material called a hydrogel. The material is capable of securely fastening objects together even when immersed in salty water— a challenge for existing adhesives. To show off its properties the researchers applied it to a rubber duck, which stuck f...
00:45 The deepest ecosystem ever discovered Researchers have dived down to more than 9,000 metres below the surface of the Pacific and discovered surprisingly complex communities of life living in deep ocean trenches. The new research shows an array of animal life that appears to be using methane as a source of energy. The researchers are planning more dives to learn more about this mysterious ecosystem and how these animals can thrive despite the extreme pressure they face. Research Article: Pe...
00:46 How hot can solid gold get? A new study suggests that gold can be superheated far beyond its melting point without it becoming a liquid. Using an intense burst from a laser, a team heated a gold foil to 14 times its melting point, far beyond a theoretical limit put forward in previous studies. The team suggest that the speed at which they heated the gold allowed them to shoot past this limit, but there is scepticism about whether the team actually achieved the level of heating they report....
A simple methodological error meant that for years researchers considered drinking moderate amounts of alcohol to be healthy. Now plenty of evidence suggests that isn't the case, but errors like this still plague the scientific literature. So, how can the scientific literature become more error-free? In the first episode of this two-part series, to determine what steps can be taken to help clean up science we explore peer review, replications, AI and even paying people to detect errors. This epi...
In this episode: 00:48 The ancient mega-predator with a ‘stealth mode’ The extinct marine mega-predator Temnodontosaurus had specialised adaptations to stealthily hunt its prey, suggests an analysis of a fossil flipper. Although Temnodontosaurus was a member of a well-studied group of marine reptiles called ichthyosaurs, its lifestyle has been a mystery due to a lack of preserved soft tissue. Now, a team have studied the fossil remains of a fore-fin, revealing several anatomical details that lik...

00:48 The past 35,000 years of disease Ancient DNA evidence shows that the advent of agriculture led to more infectious disease among humans, with pathogens from animals only showing up 6,500 years ago. The DNA, extracted from human teeth, shows the history of diseases present in Eurasia over tens of thousands of years. The approach used could be a powerful way to understand how illness has shaped humanity, but it is unable to detect some bacteria that enter the bloodstream at low concentrations...
